Preamplifiers for PSDs
Amplifiers for PSDs, Differential Diodes, and Quadrant Diodes
There are three varieties of preamplifiers available for position-sensitive detectors (PSDs).
- SPC PSD: In these small complete modules the electronics are either integrated directly on the back side of the PSD housing or are available as a small evaluation board without a mounted PSD.
- LC-301PSD, LC-301DQD: OEM module: Preamplifier boards for one and two-dimensional PSDs with three amplifier stages. More flexibility than in SPC evaluation boards.
- OT-301 Laboratory units: Flexible laboratory unit for PSDs, differential and quadrant diodes. Seven amplifier stages.
SPC PSD with Evaluation Board
SiTek’s SPC PSDs can also be supplied with an evaluation board, which makes the detectors much easier to use. The detector is mounted onto a small PCB. All input and output signals are connected by a 14-pin plug.
LC-301PSD, LC-301DQD
Amplifier boards that are particularly easy to use and very flexible. The integrated timer allows the direct connection and synchronization of a laser/LED in order to generate the light spot which is to be positioned. To adjust to the intensity of the light source, the transimpedance amplifier (TIA) has three levels of operation. Customer-specific solutions are also available.
OT-301 Laboratory Unit
The OT-301 is used in signal detection and signal processing. The versatile position sensing amplifier is an inexpensive four-channel amplifier system for all one and two-dimensional position-sensitive detectors as well as dual and quadrant detectors.
The suitable OT-302 display module contains a display for easy readout and an RS-232 interface to easily adjust individual parameters.
